Abstract:

In this paper we will investigate the sound field of a round turbulent jet with a Mach number of 0.6 based on the jet centerline velocity and the ambient speed of sound. The sound field is obtained by solving a wave equation for the acoustic field. Two different acoustic source terms are used as right hand side of the wave equation. One in which the source term is given by traditional Light hill stress tensor and a second one in which the source term is based on the vorticity in the fluid.
